Answer:
[tex]\frac{x^2}{36}=y^2+z^2[/tex]
Step-by-step explanation:
If we loo at the xy plane and consider the point (6y, y, 0), it looks like a circular path that is a cone as the curve is rotated about the x axis. The equation of the cone has the form:
[tex]\frac{x^2}{c^2}=\frac{y^2}{a^2}+\frac{z^2}{b^2}[/tex]
Given that x = 6y, to make the equation to be in the form as seen above, we square x = 6y, hence:
x² = (6y)²
x² = 36y²
The path parallel to yz axis are circles, so the equation should be as that of a circle. We need to add 36z², hence:
x² = 36y² + 36z²
[tex]\frac{x^2}{36}=y^2+z^2[/tex]
[tex](\frac{x}{6})^2=y^2+z^2[/tex]
This equation is that of a circle with radius of r = y = x/6, the resulting surface is that of a cone

Does meditation cure insomnia? Researchers randomly divided 400 people into two equal- sized groups. One group meditated daily for 30 minutes, the other group attended a 2-hour information session on insomnia. At the beginning of the study, the average difference between the number of minutes slept between the two groups was about 0. After the study, the average difference was about 32 minutes, and the meditation group had a higher average number of minutes slept. To test whether an average difference of 32 minutes could be attributed to chance, a statistics student decided to conduct a randomization test. She wrote the number of minutes slept by each subject in the study on an index card. She shuffled the cards together very well, and then dealt them into two equal-sized groups. Which of the following best describes the outcome?
Answer:
this is very long be shot question
Step-by-step explanation:
The best outcome will be that the average difference between the two sacks will be about Zero minutes.
Randomization TestAs per the question, at the beginning of the study the average difference was seen as 0 minutes, but after the experiment the average difference was of 32 minutes.
To Cross examine the study result, the researcher recorded the number of minutes slept on an index card and shuffled the cards into two equal parts. There can be three outcomes of this test, these are:
The average difference will be about 0 minutes. The average difference will be more than 32 minutes.The average difference will be about 32 minutes.There is three outcomes because of shuffling of the cards.

2x +8 x^2 +3x -4
Answer:
A) x(x-4)(x-1)/2(x+4)
Step-by-step explanation:
(x²-16)/(2x+8) * (x³-2x²+x)/(x²+3x-4)
factor
(x+4)(x-4)/2(x+4) * x(x-1)(x-1)/(x+4)(x-1)
You can take out both (x+4) from the first side, and both (x-1) on the second side. Then you’re left with:
(x-4)/2 * x(x-1)/(x+4)
which equal
x(x-4)(x-1)/2(x+4)

what is 7 1/3 as a improper fraction
Answer:
22/3
Step-by-step explanation:
First, I multiplied 7 and 3 because 7 is the whole number and 3 is the denominator of the fraction.
7*3=21
Then, I added 21 to 1 because 1 is the numerator in the fraction.
21+1=22
Finally, I made it 22/3 because the denominator of the fraction is 3.
So, your final answer is 22/3.
[tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as 22/3.
What is fraction? What are mixed fractions?A fraction is expressed in the form of {x/y}, where {y ≠ 0}. For example, we can write 2.3 in the form of fraction as : 2.3 = 23/10 and, we can write 2.2 in the form of fraction as : 2.2 = 22/10 = 11/5Mixed fractions are of the form : [tex]$x\frac{y}{z}[/tex]We can simplify them as : (z × x + y}/zGiven is to write 7 1/3 as a improper fraction.
An improper fraction is a fraction where the numerator is greater than or equal to the denominator. We can write that for a fraction {x/y} to be improper, the following conditions should be fulfilled -
{x} > {y}
or
{x} ≥ {y}
We can write 7 1/3 as a improper fraction as -
[tex]$7\frac{1}{3}[/tex] = [tex](3\times7+1)/3[/tex] = [tex]$\frac{22}{3}[/tex]
Therefore, [tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as [tex]$\frac{22}{3}[/tex].

If 4700 bricks each of size 25 cm x 16 cm x 10 cm are required to construct a wall
20 m long and 20 cm wide containing two windows of size 2 m X 1.5 m each, find
the height of the wall.
Answer:
970 cm
Step-by-step explanation:
Given that:
Size of brick :
25cm × 16cm × 10cm
Number of bricks = 4700
Dimension of wall = 20 m long × 20 cm wide
Let the height = h
Hence, dimension of wall (length and height)
2000 cm × h
Dimension of window = 2m × 1.5m = 200cm × 150cm
Number of windows = 2
Total area covered by windows = 2 * (L * B)
= 2(200 * 150) = 60,000cm
Brick = (25 * 16) * 4700 = 1, 880, 000 cm ( length and height)
Wall = 2000 * height - 60,000 = 1880000
2000height - 60,000 = 1880000
2000height = 1880000 + 60,000
2000height = 1940000
Height = 1940000 / 2000
Height of wall = 970 cm

If B is the midpoint of AC. AB = 4v and AC = 5v + 24. what is BC?
Answer:
v+24
Step-by-step explanation:
I first drew a line with A in one side and C in the other side. Then, I put B in the middle, as it is the midpoint. Under AB, I put 4v, and under AC, I put 5v+24. To get BC, you must subtract 5v+24 and 4v. I did 5v+24-4v. All I really had to do was subtract 4v from 5v which gave me v, since I can only subtract like-term numbers. Anyway, after that, I got v+24.

A book has 89 pages, but the page numbers are printed incorrectly. Every third page number has been omitted, so that the pages are numbered 1,2,4,5,7,8,... and so on. What is the number on the last printed page?
Answer:
89
Step-by-step explanation:
There are only 30 pages but last page number is 89.
The last page of the book would be with the number 89. For details, check the calculations below.
Number SystemThe number system is characterized as the arrangement or sequence in which the numbers are arranged in a mathematical order beginning from 0 in whole numbers.
In the given situation,
We know that,
Total pages available in the book = 30
And every third page is omitted from the book due to misprinting of the page numbers.
If we divided 90/3 = 30 pages are there. Hence, the last page would be 89 itself.
